The medical business of China Post Logistics is developing day by day. China Post Logistics have been using the Parallel partition picking mode for a long time, but too many shortages have appearing in these two years, especially in the order picking cost and efficiency. This paper analyzes the current order picking mode of China Post Logistics and compare with the Parallel partition picking mo...

This paper proposes a universal method, Boost Picking, to train supervised classification models mainly by un-labeled data. Boost Picking only adopts two weak classifiers to estimate and correct the error. It is theoretically proved that Boost Picking could train a supervised model mainly by un-labeled data as effectively as the same model trained by 100% labeled data, only if recalls of the tw...

BACKGROUND AND OBJECTIVES Changes in ESRD reimbursement policy, including proposed bundled payment, have raised concern that dialysis facilities may use "cherry picking" practices to attract a healthier, better insured, or more adherent patient population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS As part of a national survey to measure beliefs about drivers of quality in dialysis, respon...

BACKGROUND AND AIMS Excoriation (skin-picking) disorder (SPD) is often conceptualized as a behavioral addiction in which aberrant reward processing may play an important role. The current study sought to develop a self-report instrument--the Skin Picking Reward Scale (SPRS)--that measures how strongly skin picking is 'liked' (i.e., the degree of pleasurable feelings while receiving the reward) ...

We present a two-phase model for planning and scheduling of order picking processes. In many warehousing environments order picking processes are organized according to the pick&pack principle. Pickers must build stabile loads during the picking process under strict time constrains. A genetic algorithm with Pareto elitist-based selection has been developed for this multi-criteria optimization p...

In manual order picking systems, order pickers walk or ride through a warehouse in order to collect items requested by customers. The performance of such a system is significantly dependent on its layout which determines the lengths of the order pickers’ tours and the corresponding picking times. Whereas for classic warehouse layouts all picking aisles are arranged in parallel to each other, in...
